Malnutrition and peak expiratory flow rate
European Respiratory Journal, 1988In order to assess the effects of malnutrition on the growth of lung function, 376 Indian schoolchildren aged 6-12 yrs were studied. Peak expiratory flow rate (PEFR) was measured with a Wright peak flow meter, and nutritional status assessed by calculation of the percentage predicted height for age (HFA) and weight for height (WFH) using Harvard ...

Peak expiratory flow rate in normal pregnancy
Obstetrics & Gynecology, 1997To determine whether peak expiratory flow rate changes with pregnancy and advancing gestation.We measured the peak expiratory flow rate in 57 women during each trimester of pregnancy and postpartum. During four visits, all subjects exhaled forcefully three times into a peak flow meter.

How to use peak expiratory flow rate
Archives of disease in childhood - Education & practice edition, 2017Asthma is the most common chronic disease of children worldwide.1 The most recent National Institute for Health and Care Excellence asthma guidelines explicitly state that asthma should not be diagnosed on symptom history alone. It calls for spirometry and peak expiratory flow rate (PEFR) assessment to assist in making the diagnosis.

A Curvilinear Nomogram of Peak Expiratory Flow Rate for the Young
Journal of Asthma, 2012Peak expiratory flow rates (PEFRs) differ among populations and between times. The new EU scale of the mini-Wright flow-meter has been introduced since 2004. This study updated the PEFR nomograms with the new scale for Chinese children and adolescents (aged 6-19 years) in Hong Kong.A convenience sample was recruited from 34 primary care practices ...

Peak expiratory flow rate and rate of change of pleural pressure
Respiration Physiology, 1973Abstract It has been suggested that the sudden collapse of the large intrathoracic airways occurring at the onset of a forced expiratory manoeuvre produces an airflow contributing appreciably to the peak expiratory flow rate (PE/.VR). If so, one expects that PE/.VR will depend, not only on alveolar pressure, but also on the rate of change of pleural ...

Use of Peak Expiratory Flow Rates in Treating Patients
Archives of Pediatrics & Adolescent Medicine, 1986Sir .—We found the article by Sly et al 1 to be very important. In a similar study that was carried out a few months ago in Greece, we checked the reliability of diary cards compared with peak expiratory flow rates (PEFR) measured at home by 33 asthmatic children aged 6 to 11 years (mean, 8.2 years).

Definition of Respiratory Sarcopenia With Peak Expiratory Flow Rate
Journal of the American Medical Directors Association, 2019Respiratory muscle strength decreases with advancing age, and respiratory muscle dysfunction may indicate respiratory sarcopenia. However, there is no consensus regarding the definition of respiratory sarcopenia. We aimed to create a definition of respiratory sarcopenia based on the peak expiratory flow rate (PEFR).Cross-sectional study.Community-based

The forced expiratory volume and the peak expiratory flow rate in pneumoconiosis
British Journal of Diseases of the Chest, 1966Summary One hundred and sixty men with coal-miner's pneumoconiosis were studied in two groups to ascertain whether a good correlation existed between the F.E.V. 1 and the P.E.F.R. The first group consisted of 100 miners without chronic bronchitis and the second of 60 miners with chronic bronchitis. Correlation was good in both groups.

Factors affecting the peak expiratory flow rate in children
British Journal of Diseases of the Chest, 1984Standing height and peak expiratory flow rate (PEFR) were measured in 339 British schoolchildren aged 7-16 years. Enquiry was made into a past history of wheeze or atopy, a family history of asthma or atopy, or a cold within the preceding 2 weeks. A strong correlation was found between PEFR and height, expressed by the equation PEFR = 5.640 Ht - 472.5 (

Peak Expiratory Flow Rates in Possible Occupational Asthma
Chest, 1991Objective criteria for interpretation of peak expiratory flow rate readings were assessed in 50 patients evaluated for suspected occupational asthma who had at least two weeks of PEFR readings and an objective diagnosis based on other investigations. The prevalence of OA was 36 percent.
